Frequently Asked Questions - Chimney Cleaning in Miami, FL

Pricing & Cost FAQs
A standard chimney sweeping in Miami runs $149 to $229 for a single flue with no major buildup or access problems. Homes with two flues, a steep roof, or heavy creosote glaze typically land between $250 and $400. You get a written price before any work starts, so the number we quote is the number you pay. We don't add surprise fees after the fact. For an exact quote, call (850) 787-8597 and describe your fireplace or stove setup.
Miami's humidity is the main driver. Moist coastal air speeds up creosote hardening inside flues, and many Miami homes have decorative chimney caps, tile roofs, or stucco-clad stacks that take extra care to access safely. Roof pitch and chimney height also vary a lot between neighborhoods like Coral Gables and Kendall. A sweep that takes 45 minutes in a dry climate might take 90 minutes here. You're paying for time on the roof and the skill to do it without damaging tile or flashing.
No. Every sweep we perform in Miami includes a camera inspection of the flue at no additional cost. We show you the footage on the spot, and we email you the photos and a written condition report afterward. You see exactly what we saw. That's the whole point of The Kingswell Way: the sweep that shows you the flue. If we recommend a repair, you'll have the images to back up the recommendation and you can get a second opinion from anyone you like.
The four things that move the price are the number of flues, the amount of creosote buildup, roof accessibility, and whether repairs are needed. A single-story ranch in Hialeah is faster to service than a three-story Mediterranean-style home in Pinecrest with a steep clay tile roof. Heavy creosote takes longer and may require rotary cleaning tools. Damaged caps, failing mortar, or a cracked liner all add repair costs. We price all of it before we begin, in writing.
Yes, because the risk doesn't come from how often you use the fireplace. It comes from what builds up when you do use it, and what moves into the flue when you don't. In Miami, that includes humidity-driven creosote hardening, nesting debris from birds, and rust on metal components. A single chimney fire can destroy a flue and threaten the house. A $149 to $229 sweep is cheap insurance against a five-figure repair. If you use the fireplace at all, sweep it once a year.
Service & Process FAQs
We start by protecting the area around your fireplace with drop cloths and a HEPA vacuum. Then we sweep the flue from the roof or from inside, depending on access. After sweeping, we run a camera through the flue and show you the footage. We check the cap, crown, flashing, damper, and firebox. You get a written report with photos. The whole visit usually takes 60 to 90 minutes for a single fireplace. We leave the room cleaner than we found it.
Most single-flue sweeps in Miami take between 60 and 90 minutes from setup to cleanup. A two-flue home or a chimney with heavy glazed creosote can take two hours or more. Steep roofs and high chimneys add setup time because we anchor and stage equipment carefully. We give you a real arrival window when you book, and we show up in that window. You'll know before we start how long the job should take.
Yes. Gas fireplaces produce less creosote than wood, but they still accumulate dust, pet hair, spider webs, and light soot inside the flue and around the logs. We also inspect the venting, the gas log set, and the damper position. A gas chimney that isn't drafting properly can push carbon monoxide into the house. In Miami homes where gas logs get used more than wood fireplaces, an annual check is still smart.
No, not when it's done properly. We lay drop cloths around the hearth, run a HEPA vacuum to capture dust at the source, and seal the firebox opening while sweeping when possible. The Kingswell Way includes one non-negotiable rule: leave the place cleaner than we found it. If you've had a messy sweep in the past, that's a sign the crew skipped basic setup steps. We don't.
Both approaches work, and the right one depends on your roof. Many Miami chimneys can be swept from inside using a rotary system and a sealed firebox. But some flues, especially on two-story homes in Kendall or Palmetto Bay, are safer and faster to service from the roof. We'll assess access when we arrive and tell you our plan before we start. Roof work on tile or clay is done with padded ladder standoffs and care around flashing.
Once a year if you burn wood, even occasionally. The National Fire Protection Association recommends annual inspection and cleaning as needed, and Miami's humidity makes annual attention more important, not less. Creosote hardens into a glaze that normal brushing won't remove if it sits too long. If you only use a gas fireplace, every one to two years is usually fine. Call (850) 787-8597 and we'll help you set a schedule that fits your usage.
Brands & Parts FAQs
We install stainless steel liners from Copperfield and DuraFlex, two of the most respected names in the chimney industry. Both offer lifetime warranties on the liner material itself. The right choice depends on your appliance type, flue dimensions, and fuel source. We'll show you the condition of your existing liner on camera and explain whether a repair or replacement is actually needed. If a liner can wait, we'll tell you that plainly.
Yes, we use HeatShield when the flue liner has cracked or spalled but the surrounding masonry is still sound. HeatShield is a ceramic cement system that resurfaces the inside of the flue and restores a smooth, insulated, fire-resistant surface. It's often less invasive than a full liner replacement. We'll only recommend it when the camera inspection shows the damage is appropriate for that fix. You'll see the before and after footage.
We recommend stainless steel caps with a full mesh screen. Miami's coastal air destroys galvanized caps quickly, and the mesh is critical because birds and squirrels move into unprotected flues fast. A good stainless cap keeps out rain, animals, and debris while still allowing proper draft. We can match the cap to your chimney's crown dimensions and install it during a routine sweep. It's one of the cheapest ways to prevent expensive damage later.
It depends on the flue. Flexible stainless liners bend around offsets and work well for most wood and gas retrofits. Rigid liners stay perfectly straight and are typically used when the existing flue has a straight shot and the appliance requires it. DuraFlex makes both. We'll measure your flue, show you the camera footage, and recommend the right style for your specific setup. The recommendation is based on what the flue shows, not on what's convenient for us.
Licensing & Insurance FAQs
Every professional working under the Ashby Chimney Miami name is required to hold the license and insurance their state requires for chimney work. We carry insurance to protect your property while we work on it. Nathan Corliss leads the Miami branch and makes sure every job follows Ashby Chimney Sweep's standards: written pricing, a real arrival window, clean job site, and a written guarantee. If you'd like to verify coverage before we arrive, call (850) 787-8597 and we'll provide what you need.
Our technicians follow the trade standards and are trained on the inspection process we use at every Ashby Chimney location. The Kingswell Guarantee is the backbone of how we operate: the price in writing before work starts, show up in the window we gave, leave it cleaner than we found it, and a written guarantee on the work. If a repair fails inside the guarantee period, we come back and fix it at no charge. You can count on that.
Most routine sweeps and inspections don't require permits anywhere in Miami-Dade County. Major rebuilds or structural repairs sometimes do, depending on the scope and the city. If your job needs a permit, we'll tell you during the estimate process and explain exactly what's required. We won't start structural work without the proper approvals in place. For questions about your specific project, call (850) 787-8597.
Emergency & Response FAQs
Get everyone out of the house and call 911. A chimney fire sounds like a freight train or loud popping, and you may see flames shooting from the top of the stack. Do not try to extinguish it yourself. Once the fire department clears the scene, call us at (850) 787-8597 to inspect the flue before you use the fireplace again. Chimney fires often cause hidden damage to the liner and mortar that isn't visible from the outside.
We work Monday through Friday from 7:00 AM to 7:00 PM, and Sundays from 7:00 AM to 7:00 PM. When you call, a live coordinator will take your details and connect you with the local team to schedule the earliest available appointment. We don't promise same-day service, because every job gets the time it needs. What we do promise is a real arrival window and a crew that shows up in it. Call (850) 787-8597 and we'll get you on the schedule.
Smoke backing into the house is a sign of a drafting problem, and it needs attention before you burn again. Common causes include a cold flue, a closed damper, a block of debris, or a chimney that's too short for Miami's wind patterns. Carbon monoxide can accumulate when a flue isn't drafting. Stop using the fireplace, open a window, and call (850) 787-8597 to schedule an inspection. We'll find the cause and show you the fix on camera.
Open windows, evacuate the house, and call 911 or your gas utility if you feel dizzy or sick. Carbon monoxide is invisible and odorless, and a detector going off is never a false alarm to ignore. After the house is cleared, call (850) 787-8597 to schedule a full chimney and venting inspection. Blocked flues, damaged liners, and poor drafting are common causes of CO intrusion from fireplaces and gas logs. We'll show you exactly what's happening in the flue.
Warranty & Guarantees FAQs
The Kingswell Guarantee is simple: every job gets a written price before any work starts, a real arrival window, a clean job site, and a written guarantee on the work. If a repair fails inside the guarantee period, we come back and fix it at no charge. The guarantee is in writing, every time. That's the standard every Ashby Chimney location works to, including ours here in Miami. You shouldn't have to trust a handshake when it comes to fire safety.
The sweep is covered by our promise to leave the flue clean and show you the proof on camera. If you're not satisfied with the condition of the flue after we finish, we'll make it right. That's part of The Kingswell Way. Repairs get a written warranty with a clear time period. If something we fixed fails inside that window, we come back and fix it at no charge. No fine print games.
Yes. Copperfield and DuraFlex stainless liners both carry manufacturer warranties, typically lifetime on the liner material itself. The HeatShield system also comes with a manufacturer warranty on the resurfacing work. We'll explain the specific warranty terms for the product we recommend before you commit. Your paperwork will include both our written guarantee and the manufacturer's warranty, so you know exactly what's covered and for how long.
We'll show you the problem on camera and explain what happened, whether it's age, weather, or something else. Then we'll give you a written price for the fix. Nobody likes surprise repair bills, which is why we document everything and explain the condition of the flue in plain language. If you're unsure whether to proceed, you can take the photos and report to a second opinion. We'd rather you feel confident in the decision than rushed into it.
